Alternaria cassiae Jurair & Khan was recorded on seeds of sickle senna(Cassia tora L.). Seed infection ranged from $25{\sim}45%$ in two samples. Developing roots and shoots turn brown and died in case of severe infection. Detailed descriptions were given on the habit characters of the fungus and on the morphology of conidiophores and condia. This is the first report of A. cassiae on seeds of Cassia.

The purpose of this study is to present new design for religious habits which represen traditional Korean characters as well as prope charisms of religious congregations. The preliminary research was carried out through questionnaires. The result of this survey suggests the way how to improve the design of habits as follows: 1. The habit has to be simple according to the spirit of vowed poverty. 2. It is necessary to take into consideration the reality of Korean culture and the climate with four seasons 3. The habit is to be of help to give witness to evangelical life and safeguard the dignity of the religious state. 4. It has to be appropriate to the environment and circumstance of apostolic mission. 5. It has be funtional and conducive to apostolic activities and labors. 6. The design has to be such as will not alienate ordinary people. 7. It should express the charism of each religiou congregation as well as Korean identity. Consquently four types of inculturated habit design were newly developed and actual dresses or suit have been manufactured as a apart of this study.

Germination characters of the lettuce seed that received photoperiodic pretreatments of low or high temperature from the flowering to harvest. MSU-15 seed, one of the lettuce cultivars used, having high dark germination, was modified to low dark germination by the long-day treatments during the seed formation. Light-requiring MSU-16 seed was modified to the dark-germination seed by high temperature given at the seed formation period. Above results suggest that the environmental conditions given to an immature seed adhered to a mother plant bring about some modification to its native germination habit. I confirmed that the spectral quality of light could influence the phytochrome system which controlled germination characters of the progeny of lettuce seed ; plants grown in light rich in far-red energies produced light-requiring seed, but those grown in high deficient in far-red energies produced dark germination seed.

A total of 67 watermelon accessions which include 37 accessions from Korean and 27 accessions from Turkish germplasm and 3 accessions of other related species from USA were investigated for morphological characteristics. The UPOV descriptor list for 56 characters (6 seedlings, 4 plants, 11 leaves, 5 flowers, 23 fruits and 7 seeds) was used in characterization. In addition, eight quantitative characters, hypocotyl length, cotyledon width, cotyledon length, fruit weight, fruit length, fruit width, thickness of outer layer of pericarp and soluble solid content were also measured. The 56 qualitatively scored characters were analyzed by principle coordinate analysis (PCoA) while the eight quantitative ones were subjected to principle component analysis (PCA). Morphological characterization result demonstrated that the accessions displayed high morphological diversity(how much percent?). A high level of phenotypic diversity was observed from the results of morphological characterization. However, plant growth habit and leaf blade flecking showed constant characters for all of the accessions. The Korean and Turkish watermelon genotypes are diverse groups and can be separated by both multivariate analysis of morphological characters although the grouping was more apparent in PCoS results.

참깨 (Sesamum indicum L.) 종자로 부터 Alternaria longissima가 최초로 낮은 빈도로 검출되었다. 본균의 종자 및 WALM위에서의 생육상, 분생포자의 형태 그리고 배양적 성질을 상세히 검토하였다. 일반적으로 병원성이 없는 것으로 알려진 본균이 참깨에 심한 병원성을 나타내어 잎, 줄기 및 꼬투리에 점무늬 및 괴사의 병징을 나타내었으나 벼 및 수수에는 병원성이 없었다. 배양특성과 병원성 조사결과 참깨에서 분리된 Alternaria longissima는 Deighton & Macgarvie가 벼 및 수수 등에서 분리한 균과는 다른 계통으로 제안하고자 한다.

We investigated the variations of the flowering response to daylength in Perilla crop (var. frutescens). Seventeen accessions of Perilla crop and one accession of weedy type of var. crispa from China, Korea and Japan were cultivated under three daylength conditions, i.e., short-days, natural daylength and long-days. Most accessions of Perilla crop from China, Korea and Japan were divided into three types, early maturing type, intermediate maturing type and late maturing type by their natural flowering habit. In most of the accessions used, the flowering habit was significantly accelerated by short-day conditions and was delayed by long-day conditions. All the accessions of Perilla crops flowered within 57 days under the 10 hrs light treatment, whereas they did not flower at all even at 170 days after sowing under the 16 hrs light treatment. Thus, this finding suggested that there is a relationship between the types of flowering response to daylength and the geographical distribution which determines the planting season in traditional cultivation practices of Perilla crops. Positive correlation was observed between days to flowering and plant height or internode number in both the short-day and natural daylength conditions. Whereas, correlation was negative between days to flowering and inflorescence length or floret number in natural daylength condition, but it was positive in the short-day condition. Therefore, the daylength condition is considered as the most important environmental factor for flowering habit and morphological characters of Perilla crops. Flowering habit is considered as an important key character for the study of geographical differentiation of Perilla crop in East Asia.

For the life quality improvement of rural elderly family placed in risk of frail, this study was investigated. Health habit, food habit, and dietary management were analyzed between elderly and middle aged family The subjects 1870 collected in 9 provinces 88 cities or guns by sampling with probability proportional to size(PPS). Questionnaire method was used. Survey was conducted by trained interviewers. Statistical analyses were performed using SAS(version 8.1). Chi-square tests and General Linear Models were used. The elderly families' characters were odd pair$(42.0\%)$, with patients$(17.6\%)$ and health examination per 1 or 2 years$(44.0\%)$. The elderly families' health habit: high of no-drink$(55.2\%)$ and low of smoke$(31.3\%)$ situation was better than those of middle aged families'. The states of diets of elderly family: having breakfast$(94.1\%)$ but 1-2 kinds$(17.7\%)$ or 3-4 kinds$(59.4\%)$ of side dishes allowed to guess lower status of food intake balance. Nutritional supplements$(27.5\%)$with tablets of vitamins$(63.5\%)$ were the most frequent states in elderly family. The aspects of dietary habit of elderly family: no instant foods$(72.6\%)$, no snack$(3.08\%)$ and no dine-out$(67.7\%)$ were significantly different with those of middle aged family. Dietary habit score(8.28/12 points) of elderly family was not significantly different with 8.22/12 points of middle aged family. Food purchase place of elderly family was mainly at traditional market$(43.6\%)$, but it was significantly different with super-market$(47.6\%)$ of middle aged family. In elderly family, traditional dish preparation was seldom$(49.8\%)$ except winter kimchi$(91.5\%)$, but significantly higher rate of in middle aged families' traditional dish preparation and winter kimchi$(94.5\%)$. From these results, more of snack, traditional dishes and dine-out were needed to improve quality of life for rural elderly.

쥐손이풀속(subgenus Geranium) 35분류군에 대하여 외부형태학적 형질인 생육지, 뿌리, 줄기의 습성과 분지 형태, 엽서, 엽형, 엽연의 모양, 잎열편과 소열편의 형태, 열편의 갯수, 잎의 두께와 엽질 및 탁엽의 형태 통의 영양형질을 조사하고, 이들의 분류형질로서의 타당성 및 진화경향성을 논의하였다. 잎이 3열편으로 갈라지는 특징에 의해 Wilfordii군이, 생육지가 고산지역인 Farreri군이 나누어지며, 일년생인 특징에 의해 Maculatum군이 구분되어진다. 잎의 배열상태가 호생인 G, tripartitum, G. eriostemon, 및 G. erianthum이 나머지 분류군보다. 원시적이고, 열편이 깊게 갈라진 Sibiricum군과 Pseudosibiricurn군이 보다 분화한 분류춘이라고 생각된다. 본 분류군에서는 잎의 엽형과 소열편의 분 지정도 및 엽연의 모양과 열편의 갯수 등은 개체군 사이에서도 변이의 폭이 일정해 종을 구분하는 좋은 식별형질이라고 사료된다.
